Hello,
I tried to open a file on my linux host machine via vxworks function open("filename", O_CREAT|O_WRONLY, 0644) from target ME5100. When I run the start file st.cmd ,it printed "undefined symbol: O_CREAT". Which supprot should add to the vxworks kernel image?
Thank you in advance!

O_CREAT is a macro that should be defined when you #include <fcntl.h>.
Didn't you get any compiler warnings? They are often more useful than
errors from the loader.
Didn't you have any problems with O_WRONLY? O_CREAT and O_WRONLY are
defined in the same file!
